Ratha Yatra in Madrid, Spain (Album with photos)
Srila Prabhupada: Krishna and the sound vibration “Krishna” are no different, so if one loudly vibrates Hare Krishna, he will be able to think of Krishna immediately. This process of chanting is the best process of self-realization in this age; therefore Lord Caitanya preached it so nicely for benefit of all humanity. (Srimad-Bhagavatam, 3.24.35 Purport)
